[A case of liver nocardiosis associated with Crohn's disease while treating infliximab].

A 23-year-old man, complaining of chronic diarrhea, was given a diagnosis of Crohn's disease. He responded well to steroid therapy and infliximab administration. However, high fever appeared on the 28th day of hospitalization, and CT scan revealed multiple liver abscesses. Gram-positive branched rods were harvested by ultrasonography guided puncture examination. As Nocardia infection was suspected, sulfamethoxazole-trimethoprim was started immediately, and his clinical course improved dramatically. Afterwards, Nocardia farcinica was isolated from the culture of the liver abscess. This case is the first report of liver nocardiosis associated with Crohn's disease. Generally, Nocardia infection can be successfully treated by sulfamethoxazole-trimethoprim therapy. Liver nocardiosis is very rare but could be an important complication for patients with Crohn's disease.

Cerebral hemorrhagic infarction was diagnosed subsequently after high-amplitude slow waves detected on processed electroencephalogram during sedation: a case report.

BACKGROUND: Continuous electroencephalogram (EEG) monitoring is useful for assessing the level of sedation and detecting non-convulsive epileptic seizures and cerebral ischemia in the intensive care unit. This report describes a case of cerebral hemorrhagic infarction diagnosed after the detection of high-amplitude slow waves on processed EEG during sedation. CASE PRESENTATION: A 68-year-old man who underwent cardiac surgery was sedated in the intensive care unit following an invasive procedure. High-amplitude slow waves appeared on processed EEG monitoring before the detection of anisocoria. Computed tomography revealed a cerebral hemorrhagic infarction. CONCLUSIONS: In the management of critically ill patients, continuous EEG monitoring with forehead electrodes may be useful in the early detection of brain lesions.

Barbiturate Induction for the Prevention of Emergence Agitation after Pediatric Sevoflurane Anesthesia.

OBJECTIVES: Emergence agitation (EA) is a common and troublesome problem in pediatric patients recovering from general anesthesia. The incidence of EA is reportedly higher after general anesthesia maintained with sevoflurane, a popular inhalational anesthetic agent for pediatric patients. We conducted this prospective, randomized, double-blind study to test the effect of an intravenous ultra-short-acting barbiturate, thiamylal, administered during induction of general anesthesia on the incidence and severity of EA in pediatric patients recovering from Sevoflurane anesthesia. METHODS: Fifty-four pediatric patients (1 to 6 years of age) undergoing subumbilical surgeries were randomized into 2 groups. Patients received either intravenous thiamylal 5mg/kg (Group T) or inhalational Sevoflurane 5% (Group S) as an anesthetic induction agent. Following induction, general anesthesia was maintained with Sevoflurane and nitrous oxide (N2O) in both groups. To control the intra- and post-operative pain, caudal block or ilioinguinal/iliohypogastric block was performed. The incidence and severity of EA were evaluated by using the Modified Objective Pain Scale (MOPS: 0 to 6) at 15 and 30 min after arrival in the post-anesthesia care unit (PACU). RESULTS: Fifteen minutes after arrival in the PACU, the incidence of EA in Group T (28%) was significantly lower than in Group S (64%; p = 0.023) and the MOPS in Group T (median 0, range 0 to 6) was significantly lower than in Group S (median 4, range 0 to 6; p = 0.005). The interval from discontinuation of Sevoflurane to emergence from anesthesia was not significantly different between the 2 groups. CONCLUSIONS: Thiamylal induction reduced the incidence and severity of EA in pediatric patients immediately after Sevoflurane anesthesia.
